Filed st. 18, 1960, Ser. No. 63,421 4 Claims. (Cl. 139-243) Thisinvention relates to an automatic double shuttle loom of the crosspicking type wherein, upon exhaustion of the weft supply in theshuttles, the empty bobbins are automatically replaced by new filledones. Looms of this type are ordinarily provided with but a singlemagazine for filled bobbins and with means by which, upon exhaustion ofthe weft in either the upper or lower shuttle, the empty bobbin isreplaced by a filled one.

In weaving certain pile loop fabrics, a fine count weft yarn is used asa dummy pick to temporarily support the pile loops, said yarn beingeventually removed after the cloth is taken from the loom. In addition,a coarse or heavier weft yarn is used in the fabric for backing. Sincethere may be a large disparity in the count of the weft yarn used in thebottom shed for the body of the cloth, and the finer temporaryloop-supporting weft yarn in the top shed, it follows that the yardageof the yarns for the respective bobbins in the top and bottom shuttlevaries in proportion, and therefore it was impractical to place thebobbins in a common supply magazine in the order of requiredreplenishment for production of fabrics of the kind referred to.Accordingly, to weave pile fabrics on the looms as heretoforeconstructed, the fine or temporary loop-supporting yarn had to bereplenished by hand and, notwithstanding automatic replenishment of thecoarse or body weft yarn, the looms were actually only semi-automatic inoperation.

Our invention has for its chief aim to obviate the necessity for handreplenishment of the fine weft in looms used in the production of loopor pile fabrics, after the manner above described. This objective isrealized in practice, as hereinafter more fully set forth, throughprovision of an auxiliary magazine for the fine yarn bobbins in additionto that for the coarser yarn bobbins, and automatic means by whichfilled bobbins are released individually from the respective magazinesand substituted for the exhausted bobbins in the respective shuttleswithout interruption in the weaving.

Other objects and attendant advantages will appear from the followingdetailed description of the attached drawings, wherein:

With more detailed reference, first more particularly to FIGS. 1-4 ofthese illustrations, the loom selected for convenience of exemplifyingour invention has a framework 15 in the lower part of which is journaleda transversely extending shaft 16 adapted to be driven from a suitablesource of power, not shown. Through intermeshing spur gears 17 and 18,respectively at opposite sides of the loom, rotary motion iscommunicated from the shaft 16 to a second transverse shaft 19 supportedin bearings, such as the one indicated at 20, atop the framework 15.Afiixed to the shaft 19 at each side of the loom is an elliptical gear22 provided with a crank pin 23 which is connected, through a link 25,to the corresponding supporting sword 26 for the lay 27. The two swords26 are secured at their bottom ends to a transverse rock shaft 28suitably supported in bearings 29 in the lower frontal part of theframework 15. Mounted on the lay 27 respectively at opposite ends areboxes 30 having vertically spaced compartments 31 and 32 for receptionof upper and lower shuttles 33 and 34. During the weaving, the shuttles33 and 3 4 are thrown crosswise of the lay 27 from opposite sides of theloom by picker sticks, whereof one is shown at 35, fulcrumed on studs 36projecting laterally from upward arms 37 fast on the rock shaft 28. Eachpicker stick 35 is actuated, through a bell crank lever 39, from ahorizontally arranged treadle arm 10 fulcrumed at 41 on the framework15, each such treadle arm being iased upwardly by a spring 42 formaintenance of a shoe 43 thereon in operative relation to picker rollers44 on a double-armed member 45 affixed to the main shaft 16.Stationarily supported upon a crosswise frame member on knife bar 49 atthe replenishing side of the loom is a gravity feed magazine 50 which weutilize for filled bobbins B Wound with a heavy weft yarn, said magazinecomprising two vertical channels 51 and 52 which serve as guides for theopposite ends of filled bobbins B, and of which the lower end or outletportions 53, 54 are sloped downwardly and inwardly of the front of theloom. Disposed crosswise between the channels 51 and 52 adjacent thelower ends thereof is a cradle 55 by means of which the bobbins B arereleasable, one at a time, from the magazine. As best shown in FIG. 5,the cradle 55 comprises a horizontal shaft 56 whereof the opposite endsare rotatively supported in bearings 57 and 58 respectively bolted tothe channels 51 and 52 and a pair of discs 59 and 60 which are afiixedto said shaft within cut-outs 61 and 62 in the lower flanges of thesloped bottom portions of said channels, said discs having roundednotches of radii corresponding respectively to those of the opposite endportions of the bobbins. Cradle 55 is normally restrained in theposition in which it is shown in FIG. 3 by a finger 63 at one end of theshaft 56 maintained in engagement with a fixed stop 65 on the channel bythe pull of a spring 66 upon an armed projection 67 at the corresponding end of said shaft. Insofar as described up to this point, the loomis substantially identical with that disclosed in US. Patent 2,111,526granted to W. F. Bird et al. on March 15, 1938. Fixedly sustained inspaced relation from the magazine 56 by a cross bar 68 is a secondgravity feed magazine 70 which is similarly composed of two verticallyarranged channels 71 and 72 for guidance of bobbins B wound with a pileloop-supporting yarn thinner or different from that on the bobbins B inthe first described magazine. As shown, the buttom end portions 73 and74 of the channels 71 and 72 of the second magazine 70 slope downwardlyand toward the declining bottom end portions 53 and 54 of the magazine50 and terminate short of the latter. Like the first magazine 50, thesecond magazine 70 is provided adjacent its outlet end with a similarcradle 75 by which the bobbins B are releaseable one at a time, saidcradle comprising a cross shaft 76 rotatively supported in bearings onthe channels, and notched discs 77 and 78 on said shaft respectivelyoccupying cut-outs in the bottom flanges of the lower sloped portions ofsaid channels. Upon release of a bobbin from the supply in either of themagazines as later explained, it comes to rest in the lower ,end of themagazine 54} where it is temporarily arrested by stop fingers 83 and 89,see FIGS. 1 and 4. The finger S3 is pendent from a shaft 85 rotativelysupported in a bracket 86 on the cross bar 68. By means of a torsionspring 87 influential upon the shaft 85, the finger 83 is yieldinglyurged toward the bottom discharge end of the magazine 50, and isrestrained normally in the position in which it is shown in FIG. 4 by astop 88 on said shaft. The stop finger 89, on the other hand, is securedto a shaft 90 rotatable in the bottom end of the channel 72 of themagazine 7 and is urged toward the bottom end of the magazine 50 by atension spring 91 acting upon a second finger 92 upon said shaft.Normally, the stop finger, 89 is restrained in the illustrated positionof FIG.

- 3 through engagement with a stud 93 on the channel 72 of the magazine70.

For transferring the released bobbin from the bottom of the magazine 50to one or the other of the shuttles there is shown a means generallysimilar to that disclosed in the Bird et al. patent hereinbeforereferred to and includes a lever 95, said lever being free on andreaching upwardly from a shaft 96 journaled in fixed bearings 97 on therail 49, and to which, at the distal end, is yieldingly pivoted agrooved hammer projection 98. Fast on the shaft 96 is a tri-arm 99whereof the two extremities 99a and 99b extend above the shaft. Acompression spring whereof one end is buttressed against the extremity99a, is disposed to cooperate With the lug 1% on the lever 95 to providea yielding connection between said lever and said tri-arm. Pivotedmedially to the pendent extremity of the tri-arm 95 is a counterweighteddagger 191 which is subject to a finger spring S so as to be normallymaintained in the position in,which it is shown in FIG. 3. Dependingupon which of the two shuttles is to be replenished, the dagger 101 isadapted to be engaged by one or the other of the two hunters 102 and 103adjustably fixed in the front end of a slide bar 104, constrained toreciprocation horizontally at one side of the loom, said bar beingconnected by a link 1615 to a crank stud 166 on an elliptical gear 107,in mesh with the elliptical gear 22 hereinbefore referred to. Supportedat one end in the framework 15 at one side of the loom and at the otherend in a fixed bearing 110 pendent from the knife rail 49, is atranverse rock shaft 111, see FIGS. 2, 3, and 10. Afiixed to one end ofa sleeve 112 free on the shaft 111 is an arm 113 which carries a roller113b adapted to cooperate with a pendent cam projection 161a on thedagger 101, the hub of said arm having a lateral projection 113a inengagement with a similar projection 114a of a collar 114 fast on saidshaft. To the opposite end of the sleeve 112 is secured an upstandingfinger 115 whereof the end is notched as at 115a so as to be engageableby a counterweighted latch 116 fulcrumed at 117 upon a small bracket 118secured to the bottom of the knife rail 49. The roller 113 at the bottomend of a pendent projection 116a of the latch 116 is arranged to theactuated, as later explained, by a bunterstud 120 on the lay 27.Normally, the latch 116 is maintained in the position in which it isshown in FIG. 3 by engagement of a lug 116b thereon with the bracket118. Free on the sleeve 112 adjacent the finger is a collar 121 which isrotatably urged in clockwise direction by a torsion spring 122 formaintenance of a tongue 121a thereon in engagement with a tongue 115i;on finger 115.

The mechanism which we have devised for actuating the cradles of the twomagazines 5t and 70 derives its motion from the lay sword shaft 28 andincludes an upright arm 125 (FIGS. 1, 6, 7 and 8) alfixed to said shaft.Pivoted intermediate its ends to the-top end of the arm 125 is a lever126. By means of a horizontal link 127 the lower extremity of the lever126 is connected to the pendent arm of a bell crank 128 fulcrumed on astud projection 129 of a bracket 130 suitably affixed to the framework15. The bell crank 128 is subject to the pull of the spring 131 and itshorizontal arm is connected by an upwardly extending link rod 132 to anarm 133 (FIG. 10) fast upon the shaft 111. The cradle actuatingmechanism further includes a lever 135 which is clamped to the sleeve112 adjacent the finger 115. As shown, the lever 135 carries a pin 136which is engaged in the slot 137a of a link 137 pivotally suspended fromthe end of a short arm 138 aflixed to one end of a rock shaft 1411supported in spaced bearings 141 and 142 (FIGS. 3, 5, and 10) on theknife rail 49. Fast on the shaft 149 between the bearings 141 and 142 isa notched arm 145 whereto is connected one end of a cord or cable 146which is retroverted about an idle roller 147 and whereof the oppositeend is connected to a hook arm 148 on the shaft 56 of the cradle 55.Theshaft 140 is normally held in position rotatively as in FIG. 5 by astop arm 149 thereon subject to a toggle spring 150. A finger 151 (FIGS.6, 7 and 8) clamped tothe link rod 132 overreaches the lateral lugprojection 152a of the collar 152 at the lower end of a rod 153 which issuspended from the horizontal arm of the small bell crank 155 fulcrumedon a small bracket 156 (FIG. 4) atop the knife rail 49 and subject tothe pull of a tension spring 157. The vertical arm of the small bellcrank 155 is connected, in turn, by a link rod 158 to a small arm 159 atone end of the shaft 76 of the cradle 75. It is to be noted from FIG. 8that the rod 153 is constrained to lateral swinging movement in a forkedguide 160 suitably aflixed tothe framework 15. Journaled in spacedbearings 161, 162 also afiixed to the framework 15, is a horizontalshaft 163 having adjacent one end thereof an upstanding finger 165 whichis adapted to engage the rod 153 from behind and thereby bring the lug152a of the collar 152 beneath the finger 151 on the link rod 132, aslater on explained.

By means which we have provided to select filled bobbins from one of theother magazines 5%, 79 for transfer of the selected bobbins to theproper shuttles 33, 34 is as follows: Mounted at different elevations onthe bracket 130 are solenoids and 171, see FIGS. 1, 6, 7, 8, 9 and 13.The armature of the solenoid 170 is connected to one extremity of atri-arm 172, the extremity 172a of which is connected to a normallyretracted bolt 173 guided for endwise sliding movement in bracket 13%}into the path of the lever 126. The extremity 17% of the tri-arm 172 isweighted and connected by a link 174 to an arm 175 on the shaft 163'.The armature of the solenoid 171 is similarly connected to acounterweighed tri-arm 176 whereof the extremity 176a is connected toanother normally retracted bolt 177 likewise guided for endwise slidingmovement in the bracket 139, at a level below the bolt 173 and likewiseadapted to be thrust into the path of the 'lever126. As shown in FIG.13, the coils of the armatures of the solenoids 170, 171 are in circuitrespectively with spring biased electrodes 1%, 181 and 182, 133 slidablein guides 184, 185 and 186, 137 in a bracket 188 (FIGS. 11 and 12) onthe knife rail 49 respectively at the levels of the upper and lowershuttle compartments 31, 32 of one of the shuttle boxes 30, and adaptedto make contact with metallic ferrules 189 and 1% on the bobbins B and Bin the shuttles 33, 34 when the weft supply on said bobbins runs out.The electric current used to energize the solenoids 170 and 171 may besupplied from any suitable source such as a battery indicated at 191 inFIG. 13.

Operation Normally, the lever 126 is swung bodily back and forth withthe lay 27 without affecting the instrumentalities interposed between itand the cradles 55 and 75 of the magazines 5% and 7G. Assume that theweft supply in the upper shuttle 33 has become substantially exhaustedand that, upon the next beat of the lay 27, the electrodes 18% and 131contact the metallic ferrule 189 on said bobbin, as a result, thesolenoid 170 is energized and the bolt 173 thrust forward to interceptthe arm 126 as in PEG. 6, the bell crank 128 being thereby movedcounter-clockwise about its fulcrum 129. At the same time, byenergization of the solenoid 179, the tri-arm 172 is moved clockwise asin FIG. 9 and a similar movement is imparted, through the links 174 and175, to the shaft 163, the finger 1fi5 thereon thus urging the rod 153sidewise so that the lug 152a of the collar 152 thereon is broughtbeneath the finger 151 on the link rod 132. By arrest of the lever 126,as just explained, and the movement of the arm 125, the link rod 132 ispulled downward due to its connection to the bell crank 128, with theresult that the rod 153 is depressed as in FIG. 6 upon engagement of thefinger 151 with the lug 152a of the collar 152. Due to the slot in thelink 137, the arm 138 on shaft 146 is not affected at this time. As therod 153 is depressed, the bell crank 155 is moved clockwise to theposition in FIG. 6 and, through the horizontal link and arm 159, thecradle 75 is turned through a partial rotation to release the bobbin Bfrom the magazine 70. The bobbin B so released rolls down the inclinedlower portions of the magazine 70 and onto the bottom inclines of themagazine 50 where it is arrested by the stop fingers 83 and 89 as inFIG. 3. During the downward movement of the link rod 132, the arm 133 ismoved counterclockwise as viewed in FIGS. 1 and 1t) and the pin 136 atthe end of the arm is moved down in the slot of the link 137 without,however, affecting the shaft 149 at this time. By actuation of the arm133 however, the shaft 111 is turned through a partial rotationcounterclockwise in H63. 1 and 10 incident to which, through the collar114-, the arm 113 and the sleeve 112 are correspondingly moved. Byattendant cooperation of the roller 11% of the arm 113 with the cam 191aof the dagger 1%1, said dagger is moved about its fulcrum and the endthereof brought to the level of the bunter 192 on the slide bar 104. Bythe same rotary shift of sleeve 112 the finger 115 is turned and thenotch 115a in the end thereof is caught by the hook of the latch 116 totemporarily hold the shaft so turned against the torsional effect of thespring 122. Accordingly, during the next beat stroke of the lay 27, thedagger 101 is engaged by the hunter 162 on the slide bar 164 with theresult that, through the arm 99, the shaft 6 is turned clockwise in FIG.3, and the arm 95 is actuated so that, through the hammer 98, the bobbinB released as above explained, is transferred from the magazine 5% intothe upper shuttle 51, the exhausted bobbin being, at the same time,displaced from said shuttle and discharged down through an opening 27a(FIGS. 3 and 4) in the lay 27.

Upon exhaustion of the yarn supply on the bobbin in the lower shuttle 32and attendant contact of the electrodes 182 and 183 with the metallicferrule 19! on said bobbin when in the shuttle box, the circuit throughthe coil of the solenoid 171 is established, causing the lower slidebolt 177 to be thrust forward to the broken line position of FIG. 9 intothe path of the lever 126. The lever 126 is thereby intercepted as inFIG. 7 with impartation this time, through the parts 127 and 128, of agreater downward movement to the link 132 and impartation, in turn, of agreater rotative shift to the shaft 111 and the arm 133. A definitepartial clockwise turn is thus communicated, through the slotted link137 and arm 138, to the shaft 140 so that the notched arm exerts a pullon the cord or cable 146 (FIGS. 4 and 5) to actuate the cradle 55 forrelease of a bobbin B from the magazine 5% said bobbin rolling down theinclines at the bottom of said magazine until arrested by the fingers 83and 89. Transfer of the released bobbin to the lower shuttle 32 iseffected in the same way as hereinbefore described in connection withthe transfer of a fresh bobbin into the upper shuttle, except that inthis instance, a greater rotative shift is imparted to the shaft 111 andhence to the arm 113 whereby the dagger 101 is positioned so that theend thereof is brought to the level of the lower hunter 1% on the slidebar 104, which bunter extends to a greater distance forwardly of saidbar than the hunter 102. Accordingly, a greater swing is imparted to thetransfer arm 95 as necessary, for transfer of the bobbin released fromthe magazine 5% as above into the lower shuttle 32.

While the preferred embodiment of this invention has been described insome detail, it will be obvious to one skilled in the art that variousmodifications may be made without departing from the invention ashereinafter claimed.
